Not sure if i under stand what you mean by 2x dynamic range. If you can vary the pump from 40-100 psi could you not just base the ratio on this or are you saying that 40-100psi is too narrow a band for the range of fuel you will need.
As i type think i understand where you are coming from but i will need to work it out on paper. Another problem is staring me in the face now tho. After reviewing some datalogs its gonna be difficult to get the mix correct by using a 0-5 volt from the map sensor when the car makes boost fast.
